A timer is set after each frame is sent before waiting an ACK for that frame, how long does the timer take to be expired?
A timer needs to be set after each frame is sent before waiting an ACK for that frame. The length of time it takes for a timer take to be expired depends on only when the first outstanding frames has expires first.
Some do take 5 min., 10 minutes, or even 48 hours while others depends on what the sender has set.
What is A timer is set after each frame about?A sender is one that is not entitled to hold a timer for each frame. It has to hold a single timer.
When a the timer expires, the sender can then resends all the frames whose ACK has not been seen or received yet. The sender often starts the timer at the time it is sending the first frame , and because of that, it is only when the timer for the first set frames expires before the sender can resend any other outstanding frames.

Why do Linux administrators prefer to give sudo access to application teams instead of letting them su to root?
Answer:
Explanation:
some distros like ubuntu do not even allow su to switch to root. furthermore the su to root is dangerous because the user becomes the all-powerful administrative account, so no warnings are issued if the application team user tries to do something system-breaking.
Suppose that you have a computer with a memory unit of 24 bits per word. In this
computer, the assembly program’s instruction set consists of 198 different operations.
All instructions have an operation code part (opcode) and an address part (allowing for only one address). Each instruction is stored in one word of memory.
1. How many bits are needed for the opcode?
2. How many bits are left for the address part of the instruction?
3. How many additional instructions could be added to this instruction set without
exceeding the assigned number of bits? Discuss and show your calculations.
4. What is the largest unsigned binary number that the address can hold?
Answer:
a ) The amount of bits required for the opcode
8 bits
2^8= 256
256>198
We get the next lower number, which is 2^7 = 128 bits, because it is greater than 198. As a result, the operation code necessitates 8 bits.
b) The number of bits reserved for the instruction's address.
16 bits
24-8 = 16
c)
65536
2^16 = 65536
Maximum number = 65535
2^15 = 32768-1

Even though it highlights it super fast, then you just press backspace once, it doesn't compare to the one where you press the "ctrl" and "backspace" key at the same time, and it makes the whole entire word disappear in the blink of an eye. But, I am not sure if anybody really knows about this trick. So, it is 50/50.

s to write a Python-program that uses training data to choose the four ideal functions which are the
best fit out of the fifty provided (C) *.
i) Afterwards, the program must use the test data provided (B) to determine for each and every x-ypair of values whether or not they can be assigned to the four chosen ideal functions**; if so, the
program also needs to execute the mapping and save it together with the deviation at hand
ii) All data must be visualized logically
iii) Where possible, create/ compile suitable unit-test
* The criterion for choosing the ideal functions for the training function is how they minimize the sum of all ydeviations squared (Least-Square)
** The criterion for mapping the individual test case to the four ideal functions is that the existing maximum
deviation of the calculated regression does not exceed the largest deviation between training dataset (A) and
the ideal function (C) chosen for it by more than factor sqrt(2

How to define function in Python?In Python, a function is a sequence of commands that performs some task and that has a name. Its main purpose is to help us organize programs into chunks that correspond to how we envision a solution to the problem.
So in an easier way we have that the code is:
def plus(a,b):
return a + b
class Summation(object):
def sum(self, a, b):
self.contents = a + b
return self.contents
sumInstance = Summation()
sumInstance.sum(1,2)
